As we all know, cleaning up the oil on the metal surface has always been a major problem in the operation of the factory. Many factories will interrupt production and operation because of improper maintenance of metal equipment, thus affecting the performance and profits of enterprises. The main reason for improper maintenance of metal equipment is that enterprises do not understand it and do not adopt the correct methods for cleaning and maintenance. In the process of cleaning, the most annoying thing is the problem of foam. Let's focus on why bubbles appear and how to eliminate them.

Surfactant is the main cause of foam in metal equipment cleaning, most of which are nonionic surfactants and some of which contain ionic surfactants. When the surfactant is adsorbed on the gas-liquid interface film, it can play the role of foaming and foam stabilization, while the degreasing agent contains a large amount of electrolyte (sodium salt), which will greatly enhance the foam stabilization of ionic surfactants.

In view of this kind of foaming problem, Xinwancheng Experimental Department has specially developed an industrial cleaning defoamer in combination with relevant product parameters, which is developed for metal surface treatment agent and its application. Mainly has the following characteristics:

(1) has high solid content, low dosage, fast defoaming and long defoaming inhibition time;

(2) it has good water solubility, can be reused after dilution, and has no side effects;

(3) Good heat resistance, chemical stability, no corrosion, no toxicity, no flammability and explosion;

(4) The performance is equivalent to that of imported products, and the price is more obvious.
